![]() ![]() Compared to Manifest V2 content blockers, Manifest V3 extensions can be less powerful due to the artificial rules limits of Manifest V3. For users, it can mean that the installed content blocker does nothing at all.ĪdGuard's new browser extension for Chrome demonstrates that content blockers are possible under Manifest V3. In fact, the developers note that even the basic filter lists, which is the primary list of AdGuard, may be disabled in the worst case, as it has more than 30,000 rules. The developers have added warnings to the extension that inform users when the rules limitation is forcing the extension to reduce the number of rules that it supports. ![]() When the limit is exceeded, only the first 5000 rules will be applied by the content blocker, while all other rules have no effect.ĪdGuard MV3 Browser takes that into account. These compete with each other then when it comes to the limits.ĭynamic rules have an even stricter limit of 5000, which includes a limit of 1000 regular expression rules. Now imagine that other extensions are installed that rely on rules. It is easy to reach the 330,000 rules limit with just one extension. Users may add their own custom rules to many content blockers or subscribe to more rules listings. The default configuration of uBlock Origin uses 80435 network filters and 45243 cosmetic filters that is already more than four times the minimum guaranteed rules limit. The number may sound like much, but when you realize that modern content blockers rely on tens of thousands of even hundred thousands of rules, the limitation becomes apparent right away. Any one extension has guaranteed access to 30,000 rules. One of the main issues of Manifest V3 is that it imposes a fixed limit of 330,000 rules for all extensions installed in Chrome. ![]() While they managed to produce a working content blocker based on Manifest V3, they concede that it has certain limitations that Manifest V2 content blockers did not have. The developers note that the new APIs of Manifest V3 caused a lot of headache during development. Good luck and stick with it.Work on the extension started in mid-2021. This will give you an idea of what AdGuard does. So if you are on say, Facebook, try turning off some or all filters, reload the page and note the changes. Note one of the items in the left column is the toolbar icon, if you click on that it explains how you can use it to change filtering preferences for any site you are on at the time. ADGUARD FOR MAC VS ADGUARD FOR SAFARI FREEPersonally I have them all ticked and it doesn’t cause any loss of function for me but Safari is not my default browser.īe assured this is a good app especially since it’s free and if Safari is your primary browser it’s probably all you will ever need. You can also uninstall this feature in this window but it is better to just untick it in the left column, this will disable it, and see what the difference is. Clicking once on any one will bring up a explanation of what it does on the right. Go to the extensions tab and you will see all your current Safari Extensions, in my case I see 8 extensions for AdGuard but really they are just seperate elements of the one extension. If you open Safari Preferences you will see a window with lots of tabs at the top. Of course this means you have to remember what you did.Īs you discovered AdGuard for Safari is an extension (to Safari). This means lots of options and preferences and really the only way to customise the app for your needs is to try each setting and see what happens. Like all good anti malware, anti phishing, ad blockers it is fairly complicated and tries to cater to varied needs of different users. So it sounds like you have a handle on it now and I understand your confusion. ![]()
